The book starts with Sandy asking SpongeBob and Patrick to help fix a crack in her rocket. They try to use tape to cover it, but it gets tangled around them. Trying to break free, they accidentally knock into the rocket and cause a large piece to fall off.
SpongeBob tries to continue helping, but Sandy insists that it would be better to turn it into an amusement ride. She makes a blueprint that SpongeBob and Patrick follow. When they are done, they open the ride to the rest of Bikini Bottom. SpongeBob and Patrick take the first turn on the ride.
In this book, Incidental 42 is green instead of orange, and Incidental 64 is purple instead of green. The latter also has a large buck tooth that he does not have in the series.
